How to delete a color theme showing for a project but no longer used? Oct 02, 2019 By Marilyn Freedberg I am trying to create a clean .story file (Articulate 360) that has only the new theme colors I created listed when I go to Design > Colors and see the ones for this project. There are color themes listed for this project at the top that are no longer applicable, they were the old colors associated with the original slides, but I can't find a way to delete them. I applied my new color theme to all slides and that has taken effect. I have also renamed the player and changed colors in the player Menu.
